A Black Friday "deal" is often a normal price next to an inflated list price. Here a RV furnace only counts as on sale when its checked price is at least 15% below its own typical price over the last 90 days, from our price history. The best-rated models are listed too, since many are good value without a sale. See deals in every category.
Prices were last checked November 4, 2026. Product prices and availability are accurate as of that date and are subject to change; the price and availability shown on Amazon or the retailer's site at the time of purchase apply. As an Amazon Associate we earn from qualifying purchases.
On sale now
No RV furnace rated 3.8 or higher is 15% or more below its typical price at the last price check (November 4, 2026). Prices are rechecked through the sales; this list updates when one drops. See the recent price changes.
